this 433 MHz radio transmitter allows you remote-controlled electrical socket controlled via the I2C bus.
The I2HFS module connects between the I2C bus and 433MHz radio outlets from different manufacturers.
About the I2C bus data is written to various registers of the card, which are then transmitted to the radio-controlled sockets via 433MHz.
To ensure compliance with the various protocols and data formats you need not worry about, this is done by the PIC controller, which is installed on the card.
